text-embedding-3-small

GA

Cost-efficient embedding model, default 1536 dimensions. Price is first-party: $0.02 per 1M input tokens, confirmed unchanged 2026-08-08 against developers.openai.com/api/docs/pricing (Standard tier, embeddings table); no output-token billing. Max input tokens CORRECTED 8191 -> 8192 on 2026-08-18: the model spec page states no limit at all, and the live API reference (developers.openai.com/api/docs/api-reference/embeddings/create) states it as a constraint on the input parameter -- "the max input tokens for the model (8192 tokens for all embedding models)". 8191 was the figure OpenAI's 2024 new-embedding-models announcement carried; the reference carries the field as data and is current, so it wins on the precision ranking. Not an upstream change and therefore no changelog entry.

text-embedding-3-small by OpenAI is tracked live in our LLM catalog, with a 8K (8192-token) context window. It is generally available (GA).
